Researchers using new simulations suggest that the Milky Way’s past collisions may have reshaped its dark matter core. This ...

Is there anything more dramatic than an exploding star? More than just extraordinarily bright, energetic events that can ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film version of ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

NASA’s Swift spacecraft has detected its 1,000th gamma-ray burst (GRB). GRBs are the most powerful explosions in the universe, typically associated with the collapse of a massive star and the birth of ...

Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and ...

A gamma ray glow at our galaxy’s center has puzzled scientists for almost two decades. New computer simulations back the ...

The orange dot at the centre of this image is a powerful explosion that repeated several times over the course of a day, an event unlike anything ever witnessed before. The image, taken with ESO’s ...

The Giuseppe and Vanna Cocconi Prize 2025 is awarded to the Fermi-LAT and Fermi-GBM collaborations for revolutionizing the field of gamma-ray astronomy. Established 15 years ago, the Giuseppe and ...

Light curve of the gamma-ray flare (bottom) and collection of quasi-simulated images of the M87 jet (top) at various scales obtained in radio and X-ray during the 2018 campaign. The instrument, the ...

In a first-of-its-kind experiment, scientists have recreated "cosmic fireballs" here on Earth in a particle accelerator.The ...
